Won't Fix

UI - Components ( e.g. Image Component) is no longer Anti Aliasing in Game view with Screen Space - Overlay canvas

Graphics - General


Antialiasing has been broken/disabled for UI elements when the canvas is set to 'ScreenSpace Overlay'.

In the example scene, the Quality is set to 8x MSAA, the camera has allowMSAA enabled, yet in-game view( and builds ) the 1 pixel line ( generated via a rotated UI image component) is no longer antialiased, however, in the scene view it is.

It's possible to set the canvas to 'ScreenSpace - Camera' and this will fix the issue, unfortunately, it breaks a lot of other code - for example, the dynamic line code in the example no longer works.

Ultimately ScreenSpace - Overlay should and needs to support the projects MSAA settings, but no longer does.

Steps to reproduce:
1. Open User's attached project
2. Edit > Project Settings > Quality. Notice: Anti Aliasing is set to 8x Multi Sampling
3. Open Scene view. Notice: "SampleLine" is perfectly antialiased and smooth
4. Open Game view. Notice: "SampleLine" image component is Aliased.

Expected result: in both Game and Scene view UI components are Anti Aliasing.
Actual result: in Game view UI components are Aliasing.

Reproduced with: 2017.2.0b2, 2017.1.0f1, 5.6.2p2.
Not reproduced with: 5.5.4p1, 5.4.5p4.

    Vector UI icons are broken too. Unity 2018.2.7f1.

    Where can I find an explanation why this won't be fixed?

    makes no sense that this won't be fixed... it is even broken in 5.6.x

    this was just a lazy closure on an issue IMO.

    Maybe they got confused by the last line: "Actual result: in Game view UI components are Aliasing." Maybe they read it as "anti aliasing" instead of "aliasing" without really knowing the difference. Well, that's my best guess anyway for marking this as Won't Fix without an explanation.

    Why is this marked at Wont fix? This is an essential feature.

    We're having the same problem. It's just UI Components, 2D Sprite Renderers are fine.
